Mendel is known as father of genetics. He explained the concept of dominance, the law of segregation and the law of independent assortment while working on pea plant.
Green seed color is recessive and yellow seed color is dominant. A pure green line seed plant (ss) is crossed with heterozygous plant (Ss). The cross is as follows:
Parents ss (green seed) × Ss (Yellow seed)
Gametes s S, s
